Introduction The stability of C-section columns with different sheathing configurations subjected to compression is the subject of this report. Column configurations with and without sheathing were tested for compressive capacity. Two types of sheathing were considered: oriented strand board (OSB) and gypsum board (GYP). The influence of OSB and GYP sheathing on the compressive carrying capacity of the columns was investigated. A total of 26 tests on short, intermediate and long columns were carried out. To examine the role of boundary conditions the top and bottom ends of the column studs were either left free or connected to tracks through screws with OSB and/or GYP sheathing attached to one or both sides of the studs and tracks. Imperfections of the columns were measured at six cross-section locations. These locations and direction of the imperfection measurements were chosen such that the possible deformed configurations of local, distortional and global buckling can be captured. For each of the columns, measurements at 75 local, 25 distortional and 8 global imperfection points corresponding to each cross-section location was carried out. To measure the deformations for analyzing the buckling failure types of these tests five position transducers were set up at the mid point of the studs for the 2, 4, 6 and 8 ft studs, in addition to two string pots used to measure local deformation at the ends for the 8 ft studs. The tests were conducted using a universal two-post 100 kip MTS and a custom built multi-degree-of-freedom (MDOF) testing rig capable of 200 kips compression and being utilized for testing of full walls in a companion research project which gave load-displacement and position transducer records to aid in understanding of the effects of different combinations of sheathings and boundary conditions on the stability of columns, and the impact of composite action of the sheathings when acting as direct load-bearing component.

Cross-section Dimension Measurements Cross-section dimension measurements of the 362S162-68 (SSMA/ASTM nomenclature) studs and 362T125-68 tracks are given in Appendix D. The dimensions of these measurements are given in Figure 1 with the following notations: H out-to-out height of web BA out-to-out flange width of side A BB out-to-out flange width of side B DA out-to-out lip height of side A DB out-to-out lip height of side B rhbA outer radius of corner near the web on side A rhbB outer radius of corner near the web on side B rdbA outer radius of corner near the lip on side A rdbB outer radius of corner near the lip on side B θhbA outer angle of corner near the web on side A θhbB outer angle of corner near the web on side B θdbA outer angle of corner near the lip on side A θdbB outer angle of corner near the lip on side B t* web / flange thickness, including galvanizing

Coupon Test

Columns and tracks where chosen randomly from the single column specimens already tested, since they used the same material. Steel plates where roughly cut from the web and outside the yielded area, the dimension entered in the CNC milling machine to precisely cut the coupon specimen is showed in Figure 2.

The specimens after cut were immersed in hydrochloric acid, concentration of 15% in volume (85% distillated water and 15% hydrochloride acid) for 10 minutes. The hydrochloride bath is necessary to remove the zinc coating and then be able to measure the specimen dimensions without the coating. Figure 3 shows the test set up and one of the specimens after tested. Two methods were used to find the yielding stress, the 0.2% offset method and the autograph method. Basically the 0.2% method consider the yielding stress equal to the stress where the stiffness line (Young’s modulus = E = 29500ksi) is offset from the origin to the 0.2% engineering strain and it intersect the stress-strain curve, on the other hand, the autograph method use the same offset technique but the lines are offset to 0.4% and 0.8% of the strain and the yielding stress is the average value in the range between the two lines. All the data is discretized and given in Appendix G. The authors consider the 0.2% offset method the most appropriate method to find the yielding stress for the steel used in the studs because there is no yielding plateau as shown in Appendix H. On the other hand, the steel used in the track has the yielding plateau and then the autograph method is more appropriate; if the 0.2% method is used to define the yielding stress the value will be a peak value as shown in Appendix I.

Imperfection Measurements Imperfections were measured via a rig synchronized with LVDT for automatic recording in labview. Local imperfection measurements (point D on Figure 4) were made at 0.5 in. spacing along a foot span at the center and either ends. Distortional imperfection measurements (points A and F) were made at 1 in. spacing along a 2 ft span at the center whereas global imperfections (points B, C and E) were recorded every foot along the length of the member. Figure 5 shows a labview window of imperfection recording for an 8 ft member. Figure 6 shows plots of web and flange imperfections along with bow, camber and twist plots of the members computed based on the global imperfection measurements for an 8 ft member. Imperfection plots of the members tested are given in Appendix E.

Sheathing Types OSB (7/16 in., rated 24/16, exposure 1) and gypsum (½ in. Sheetrock) are the two types of sheathing used. The notations used to represent the sheathing configurations in the tests are given in Table 1. All tests with sheathing include stud and tracks. The humidity level during testing was on average 62%.

Test Apparatus and Loading Details The tests were done using MTS and multi-axial testing rig MDOF machines. Compressive load was applied through the bottom load cell for the case of the MTS. The vertical displacement in the tests that use the MTS machine was measured through a position transducer in-built at the bottom load cell as shown in Figure 8. A small isolation plate was provided between the loading plate and the track for some of the tests with the MTS machine as shown in Figure 9. For the MDOF machine, compressive loading was applied through four actuators at the top and the vertical displacement was measured as the average of the vertical displacements measured through in-built position transducers in these actuators. Direction of vertical displacement, loading, and position of actuators for the MDOF machine is shown in Figure 10.

Sheathing-Stud-Track Connection Details Number 6 screws (Simpson #6 x 1 5/8’’) were used to connect to the gypsum boards and number 8 screws (Simpson #8 x 1 15/16’’) were used to connect to the OSB boards as shown in Figure 11.

Position Transducers Five position transducers and two string pots were set up at the midpoint and ends of the members respectively as shown in Figure 12 to capture local and global buckling for the different test configurations.

Discussion of Results Discussion of representative results among the tests will be presented based on configurations of sheathing, length of member, and type of boundary conditions adopted throughout the tests as follows. BARE-BARE WITHOUT TRACK 4-BARE-BARE-1S2L-2 This test was carried out for a 2ft long column with ends directly bearing against the load platens of the MTS machine. At the top end (end 1), there was a noticeable gap between the load platen and stud end as shown in Figure 13 a. As can be observed the contact with the load platen was on the lips side with

the web and flange having barely any contact. The loading rate on the MTS machine was 0.0132 in/sec. After loading for 12 kips the gap was still present though closing in and it was observed that the lips open out at the top end. Global deformation could also be observed from the beginning as the load bearing on the lips directly lead to eccentric loading as can be seen from the movement of web position transducers 3, 4 and 5. At 16 kips the gap closes with distortional buckling starting to form at the top end and continuing through the length of the member. Distortional buckling at the mid length of the member was captured by position transducers 1 and 2 as shown in Figure 13 b. As the top end’s gap closed failure was seen to be concentrated at the bottom end where there was a large imperfection. This resulted in the bottom end’s (end 2) local failure close to 21 kips. At the peak load (21.74 kips, Figure 13 c) visible distortional and web plate (local) failures were observed at the bottom end as shown in Figure 13 d.

Gaps between track and load platen and between track and stud were observed at both ends with the top end showing a larger gap

(approximately 1/16”) as shown in Figure 14 a. Distortional buckling was observed as load reached 21 kips with the channel lips distorting inward as indicated by position transducers 1 and 2 in Figure 14 b and those at the ends distorting outward. Local buckling wave at the ends was observed at 23 kips closer to the peak load. The bottom end of stud was found to have more local deformation than the top since load is applied through the bottom (or higher imperfection at this end). After peak load, weak axis global buckling was observed. The load-displacement graph given in Figure 14 c indicates more ductile response provided by the addition of tracks in this test in comparison to that shown in Figure 14c for the stud test with no tracks.

22-BARE-BARE-61S8LTP-8-T-P In this test, an 8 ft stud with tracks was axially-loaded using the MDOF machine. Weak axis flexure was observed as the load reached 12 kips (Figure 15 c). This can be seen from the three web position transducers (3, 4 and 5) as shown in Figure 15 a. The peak load was found to be 12.84 kips from the load-displacement graph in Figure 15 b. Flexural-torsional buckling was also observed along with local web plate buckling due to bending in the post-peak range as shown in Figure 15 c.

OSB-BARE WITH TRACK AND PLATE 23-OSB-BARE-62S8LTSP-8-T-S-P The sheathing configuration in this test is such that OSB is provided on only one side of the 8 ft column. Tracks are attached to the top and bottom of the stud, with small loading plates transferring load directly to the tracks i.e. no direct loading of the sheathing is allowed. The failure type observed is strong axis flexural-torsional buckling as can be seen from the movements of position transducers 4 and 5 on Figure 16 a and deformation on Figure 16 c. A peak load of 15.64 kips was observed as shown in the load-displacement plot given on Figure 16 b.

In this test, the gypsum sheathing is not in direct contact with the load platen as there is provision of a small plate to transfer load to the tracks directly. With loading close to 22.5 kips

distortional buckling was observed at the ends followed by crushing of the web at the ends at 25kips (Figure 17 c). Peak load for this specimen was found to be 25.37 kips (Figure 17 b) followed by screws popping out from the side of gypsum as can be observed in Figure 17 c.

In this test the track and gypsum bear on the load platen with no small additional plate to transfer load to track. The top end (end 2) showed initiation of web local buckling with the gypsum sheathing crushing at this end (Figure 18 c). As can be observed from Figure 18 a, position transducers 1 and 2 pick up the deformation at mid length of the member. Peak load reaches 27.66 kips as shown in Figure 18 b.

OSB-OSB WITH PLATE 26-OSB-OSB-65S8LTSP-S-T-S-P OSB sheathing on both sides of an 8 ft stud with tracks loaded through plates was considered for this test. As the load reaches 21 kips, the string pot on the top was observed to pick up the movement as shown in Figure 21 a. As the peak load approached (Figure 21 b), the bottom string pot was observed to pick up the corresponding local buckling at that end. The sign of distortional buckling at the top can be seen from Figure 21 c as screws started tilting.

SUMMARY OF RESULTS

Deformation at failure for all the tests is given in Appendix B. Appendix C and F give load-displacement and position transducers’ plots. Summary of the peak loads and failure mechanisms for the tests are given in Table 2. For the BARE-BARE configuration, the 8 ft studs showed flexural buckling failure mechanism, the 6 ft and 4 ft studs showed combination of local and global failures depending on the presence of tracks, and the 2 ft studs failed locally either in local or distortional buckling. For the OSB-BARE configuration, the 8 ft and 6ft studs failed in flexural-torsional buckling with the rest of studs failing locally at the ends. For the configurations OSB-OSB, OSB-GYP and GYP-GYP all the studs were observed to fail locally at the ends.

Figure 22 shows comparison of the peak compressive load capacities for the 2, 4, 6 and 8 ft studs connected to tracks with different sheathing configurations and loading condition such that studs carry load via isolation plate directly above the tracks. As can be seen from Figure 22, the provision of sheathing restrictions increases the capacities of these studs with OSB – OSB sheathing configuration leading to the maximum strength results and BARE-BARE configuration resulting in the minimum strength with others lying in between. Overall the performance of OSB-GYP sheathing configuration was found to be comparable to that of the GYP-GYP configuration in these observations.

The load-displacement graphs for the different sheathing configurations of the 2, 4, 6 and 8 ft studs are given in Figures 23-26. Figures 27-30 give comparison of load-displacement graphs for the different lengths of studs considered in the test. Load-displacement results for the tests examining the effect of tracks are given in Figures 31 and 32. It was observed that the presence of tracks increased the peak loads of the 2 ft by 6%, with no significant increase for the 4 and 6 ft studs. Figures 33 and 34 show the effect of bearing track on plate for OSB-OSB and GYP-GYP sheathing restrictions.
